Overview

A great step-up from brushed bashing, the 1/10 scale ARRMA® BIG ROCK™ CREW CAB 4X4 3S BLX ready-to-run monster truck delivers a thrilling combination of ARRMA® toughness, street truck style and 50+ mph speed capability. Built on the powerful 4X4 BLX platform, its precision aluminum, tough steel and composite materials come together for an easy-to-maintain, super-durable vehicle design that’s now been upgraded to further increase the monster truck’s impressive performance and durability.

The BIG ROCK™ 4X4 3S BLX is DESIGNED FAST, DESIGNED TOUGH — built for exciting bashing speeds and extreme, all-terrain durability. New features that enhance its unstoppable performance include a stronger chassis and retained hinge pin plates; steering with more clearance for stones; a castellated slipper pad and sliding gear mesh; longer suspension arms for a 1.10 inch increase in width; and rubber-shielded bearings throughout.

It also now includes a Spektrum™ SLT3™ transmitter and SLR300 receiver. The transmitter is ergonomically designed for long periods of fatigue-free bashing and has a foam wheel for precise fingertip control, plus an improved hand grip and trigger feel. New bashers will be able to set throttle limits at 50% or 75% until they are ready to use the full speed potential. The SLT3™ is compatible with Tactic® SLT™ receivers to run other RTR vehicles you may own, and includes a third channel to control optional features such as lights and winches on models that have them.

ARRMA® now powers the BIG ROCK™ 4X4 3S BLX with a brushless system featuring its BLX100 ESC and the Spektrum™ Firma™ 3200Kv brushless motor. The combination provides incredible torque, acceleration and speed. The transmission and chassis are ruggedly engineered to take full advantage of the electronics’ power.

It has the ingenious modular design perfected by ARRMA® engineers for easy component access and maintenance. The power module, with improved dirt management, consists of the motor with ARRMA® heatsink and cooling fan, plus motor plate, slipper clutch assembly and gear cover. The power module can be detached from the chassis as a complete unit by removing just one screw. With the power module removed, the slipper clutch can be reached easily for adjustments by taking out three screws that attach the gear cover. The gear ratio can be finely tuned as the power module now uses a sliding motor mesh design.

A two-piece molding screwed to the truck’s chassis serves as its electronics module, containing a waterproof receiver box, servo mount and ESC tray. The SLR300 receiver mounts inside the receiver box for protection from dirt and moisture. The ultra-compact ESC is screwed to the top of the module, allowing quick access to the on/off switch, while the servo mounts to the side. All three components can be removed together, quickly and easily.

The differential module houses each differential unit in an innovative yoke design. Only eight screws need to be removed to release the front and rear yokes. The power module can then be detached, allowing you to pivot the gearbox cases for differential access. The BIG ROCK™ 4X4 3S BLX RTR comes brushless-ready with 37T 1.35mod diffs with silicone O-rings. The large gears can withstand huge torque, and internal metal gears have been chosen for reliability during extreme bashing.

Its full-time 4WD transmission uses strong front, rear, and centerline telescopic driveshafts that can’t be lost during heavy impacts, unlike dogbones. A simple, dependable, responsive steering assembly complements the ultra-reliable drive system and features a servo horn with built-in servo saver. The BIG ROCK™ 4X4 3S BLX RTR includes the waterproof Spektrum™ SPMS651 metal-geared digital servo for 15% more torque than the previous version’s ADS-7M servo.

Testimonials


I'm new here in Pensacola and I called around to a few places to find certain things for my car. And ended up here at kings. I was amazing by the amount of product they car. And the young man behind the counter was so helpful and polite. Me and my sone got what we need and found a few other great info that we really needed.

Thank y'all so much


I live in Texas and have used King's website for a few purchases now, and every time they make sure to get my order shipped as fast as possible. Every order I have received has been packed perfectly and securely. I highly recommend them!


Great experience! They had a rare item in stock. Packaged very well and shipped promptly. I will definitely order from them again.


I’ve ordered online and now I’ve been in person. Stellar service and very knowledgeable. Corey and the guys know and love what they do. I’ll be back next year for sure!

Great Products - got my RC Porsche from them - through their ebay store - fast shipment - well packed - great service. Very happy with purchase from King Cobra!

When into the shop on a whim with my son because I’ve been wanting to get back into RC cars. We ended up walking out with an Arrma Granite Mega by recommendation of Corey. He was a great help and answered all my questions. They only thing I was dissatisfied with was I asked about the run and charge time on the battery and was told about 20-30 minutes run time depending with about an hour to recharge the battery. The recharge time for the battery is about 3.5 hours with the charger that comes with the kit. The truck is a lot of fun, great to learn on and plenty fast for my 4 year old. I would recommend immediately buying another battery or upgrading to a LiPO battery and better charger.

I purchased an Axial SCX24 online. It was a quick and easy process, quick shipping, and the only place I could find with the one I wanted in stock! I'll definitely be using them again!

I have had such a wonderful experience with these guys. Over the last few weeks I have ordered an extremely large amount of product from them and I have been taken care of on each question I've asked and each concern that I've had. The real standout of the team so far, is Amanda (Mandie). I have been on the phone with her multiple times over the last few days because of a few little questions that I've had and she has gone above and beyond to help me every single time. I feel like this is a relationship that I will have with this company for a long time and look forward to doing business with them in the future.
These days, it's hard to find customer based businesses that take things seriously and these guys have it for sure. Excellent place and very trustworthy!

Great place!! My husband and I go there almost weekly, the staff is also very helpful. If you want a family feel atmosphere where they know you by name and always very helpful swing in and say hi you won’t regret it.
